[SCSI] mpt fusion: Fix 32 bit platforms with 64 bit resources.

Powerpc 44x uses 36 bit real address while the real address defined in
MPT Fusion driver is of type 32 bit. This causes ioremap to fail and
driver fails to initialize. This fix changes the data types
representing the real address from unsigned long 32-bit types to
resource_size_t which is 64-bit. The driver has been tested, the disks
get discovered correctly and can do IO.

[jejb: added printk fix for resource_size_t object]
